When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.
What is the difference between hydro electric power and geothermal energy?
Hydroelectric energy gets energy stored in water, as potential energy, i.e., if it falls down, it can move the turbines, to produce electricity. Geothermal energy gets electricity from the heat stored in the Earth's interior.
Where does Geothermal Energy get its energy from?
Geothermal energy gets its energy from the heat stored within the Earth's crust. This heat comes from the radioactive decay of elements, residual heat from the Earth's formation, and heat from the sun absorbed by the surface.
Which energy source uses water that is naturally heated by the earths internal heat?
Geothermal Energythe term for deriving electricity from the heat of the earth is "Geothermal" (literally geo = earth and thermal = heat). Iceland gets a huge portion of its electricity from geothermal energy
Is energy released when water vapor condenses into liquid?
Yes, energy is released when water vapor condenses into a liquid. This process is called condensation, and it results in the conversion of water vapor's latent heat energy into sensible heat energy in the form of heat released to the surrounding environment.
Beaker A contains water at a temperature of 15 degrees C beaker B contains water at a temperature of 37 degrees C Which beaker contains water molecules that have greater kinetic energy and why?
Beaker A: 15 C Beaker B: 37 C Beaker B contains water molecules that have the greater kinetic energy (on average). Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average). If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average). Kinetic energy = (1/2) (mass) (velocity)^2 Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.
How does water gets energy from the sun?
Energy that water gets from the sun is most commonly absorbed in the form of heat.
How do you heat a beaker of water?
With a heat source, slowly so as to not shatter the beaker.
How does the heat reach the thermometer in the heated beaker?
Heat reaches the thermometer in the heated beaker primarily through conduction and convection. As the beaker is heated, the water molecules gain energy and transfer that energy to the thermometer through direct contact. Additionally, as the warmer water rises and cooler water descends, convection currents help distribute heat throughout the liquid, ensuring that the thermometer accurately reflects the water's temperature. This process allows the thermometer to register the temperature of the liquid efficiently.
What happens to the thermal energy in a beaker as it cools down?
As the beaker cools down, the thermal energy within it decreases. This results in a transfer of heat from the beaker to its surroundings, causing the temperature of the beaker to drop.
When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.
Why are hurricanes not stronger when the seas are cold?
Because the hurricane gets its energy from the heat in warm water, and in cooler water there is less heat and thus less energy
In an experiment what is a heat used for?
A heat is used to increase the thermal energy in whatever you are testing. In a typical classroom situation, the heat will be supplied by a Bunsen Burner, which provides a flame. This flame is then used to heat whatever object needs heating. For example, boiling a beaker of water by applying the heat under said beaker.
Why does the temperature in the ice bath remain constant for several minutes after placing the beaker in the warm water bath?
The reason that the temperature in an ice bath remains constant for several minutes after placing a beaker in a warm water bath, is that it takes water longer to heat. The cold water will not heat up right away because the energy hasn't transferred.
How do you heat a liquid to 90 degrees?
if your in a lab, put water in a beaker, place the beaker on a tripod and heat with Bunsen burner, (use thermometer to measure
Which on has more calories or heat energy a 3 gallon bucket of water or a 1 gallon?
3 gallons because it has more heat energy and it gets warmer
Where does a storm gets its energy?
From the Sun. (The Sun's energy causes water to evaporate and heat air. the latent heat of the evaporation and the hot air drive the storm).
